Regarding your last comment, my wife just read to me what William Shatner said after disembarking from the spacecraft that took him to space. In an interesting way, it's quite inspiring and share's my perspective as it has changed over the decades (he's just a little older than me).
“Oh my God. it’s indescribable, To see the blue color [of the atmosphere] shoot by like that. Down there is mother, comfort - and up there is death. Is that what death is? It is so moving. I never expected it. There’s beauty of the blue. It’s so thin. You’re going close to 2,000 mph, and through like 50 miles of it in an instant. And then you’re into black. It’s mysterious, and you know there are galaxies and such up there, but all you see is that black. And down below is light. [Jeff], what you’ve given me is the most profound experience I can imagine. I’m so filled with emotion. It’s extraordinary. I hope I never recover from this, maintain what I feel now. It’s so much larger than me. It has to do with enormity, the quickness of life and death. Oh my God! It’s beautiful in its own way. What I would love to do is communicate this as much as possible. The jeopardy, the moment you feel that vulnerability. This air which is keeping us alive is thinner than your skin. It’s a sliver, immeasurably small when you think in terms of the universe. Mars doesn’t really have it. There is life, and then there’s death."
Earth is a special place. Sure, there may be quadrillions of other planets that God created other imagers on, but as far as we're concerned, this is it.
Exoplanets are so cool, as I learned about them back in 2010 during the summer before 5th grade by reading the Astronomy periodical. Gliese 581c was my favorite exoplanet as a kid. Nowadays, periodicals are filled with too many ads.
